Estes Maxi Pershing 1A Nose Cone
 
Has anyone made a copy of the Pershing 1A nose cone that I can get, print or have printed?
I know someone made a fiberglass one years ago but it weighed a ton (figurative one, not an actual ton) I have the nice kit that Boyce made - but it's BT-80 size and I want to make a 4 inch version. I have everything but the nose cone.

Any help would be appreciated.

Thanks.

Leo DeNutz drew up these parts several years ago.

Boyce also does the Maxi-Brute BT-101 version of the Pershing 1a.

Yes, I see that now. Can?t believe I didn?t see it before.
Thanks!

The Boyce kit must need a load of nose weight. If you need a BT-101 body tube you can use the Estes Saturn V main body tube.

The Estes kit used a lot of clay in the nose as well. I remember spending quite a bit of time packing it into the nose. That was probably 45 years ago, though, so maybe I just think I remember it. :chuckle:

A friend of mine still has his built up model. He modernized it with the Boyce printed fins but he has his original nose. It flew well enough BITD. Always exciting on a D12. Thanks to more powerful motors, it gets up there so much better. I am less worried about the weight. You?re right though. It?s probably a brick.

It does indeed need a buttload of nose weight. I ended up using #8 chilled lead shot encased in epoxy.

I flew mine on a D12-3 when I was a kid. I will fly a 1/100 Saturn V or a 1/70 Saturn 1B on a D12-3 all day with no fear (calm air), but the way the Pershing flew, I decided I was very lucky to recover it in one piece. I immediately retired it and never flew it again.

I did the same thing - lead shot incased in epoxy.
To put the amount of ballast required into perspective, the CG needs to be only about an inch aft of the forward end of the main BT101 Body Tube :eek:
I didn't weight the amount of ballast I used, but the nose cone weighs as much as the rest of the rocket - and it's not a light rocket.
